<div class="jive-rendered-content"><p>I encoutered the same issue. Have you figured it out?</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Below is a mored detailed description:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I try to instrument the call in the method:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>    public static Currency getInstance(String currencyCode) {</p><p>        return getInstance(currencyCode, Integer.MIN_VALUE);</p><p>    }</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>, which is inside java/util/Currency.class. The call invokes "<strong>private static</strong> Currency getInstance(String, int)", which is enclosed in the same class as the caller.</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>I need to add some statements around the call "getInstance(currencyCode, Integer.MIN_VALUE);". So I used MethodCall.replace("{some statements; $_ = $proceed($$); other statements;}"), then I got the exception like below:</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>Caused by: compile error: Method getInstance is private</p><p>    at javassist.compiler.</p><p>MemberCodeGen.getAccessiblePrivate(MemberCodeGen.java:671)<br/>    at javassist.compiler.MemberCodeGen.atMethodCallCore2(MemberCodeGen.java:612)<br/>     at javassist.compiler.MemberCodeGen.atMethodCallCore(MemberCodeGen.java:575)<br/>    at javassist.compiler.MemberCodeGen.atCallExpr(MemberCodeGen.java:523)<br/>    at javassist.compiler.JvstCodeGen.atCallExpr(JvstCodeGen.java:244)<br/>     at javassist.compiler.ast.CallExpr.accept(CallExpr.java:46)<br/>    at javassist.compiler.CodeGen.compileExpr(CodeGen.java:230)<br/>    at javassist.compiler.Javac$2.doit(Javac.java:490)<br/>    at javassist.compiler.JvstCodeGen.atCallExpr(JvstCodeGen.java:235)<br/>     at javassist.compiler.ast.CallExpr.accept(CallExpr.java:46)<br/>    at javassist.compiler.CodeGen.atAssignCore(CodeGen.java:860)<br/>    at javassist.compiler.CodeGen.atVariableAssign(CodeGen.java:793)<br/>    at javassist.compiler.CodeGen.atAssignExpr(CodeGen.java:747)<br/>     at javassist.compiler.CodeGen.atStmnt(CodeGen.java:332)<br/>    at javassist.compiler.ast.Stmnt.accept(Stmnt.java:50)<br/>    at javassist.compiler.CodeGen.atStmnt(CodeGen.java:351)<br/>    at javassist.compiler.ast.Stmnt.accept(Stmnt.java:50)<br/>     at javassist.compiler.Javac.compileStmnt(Javac.java:569)<br/>    at javassist.expr.MethodCall.replace(MethodCall.java:235)<br/>    ... 18 more</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>The bug can be reproduced. For example, in java.lang.securityManager, the method checkPackageAccess contains a call<br/> "packageAccess = getPackages(tmpPropertyStr);", The call invokes "<strong>private static</strong> String[] getPackages(String p)".</p><p style="min-height: 8pt; height: 8pt; padding: 0px;"> </p><p>In both cases, it involves invocations to "private static" methods.</p></div>
